A girl rolls a ball up an incline and allows it to return to her. For the angle 0 and ball involved, the acceleration of the ball along the incline is constant at 0.25g, directed down the incline. If the ball is released with a speed of 4m/s, determine the distance s as it moves up the incline before reversing its direction and the total time t required for the ball to return to the child's hand.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
